For those who want P-39 ....
btw i want Japanese fighters (ki43, ki44, J2M3, Ki100) 1st!

Most representative lineup of P-39s.
P-39D U.S. Version:
245 lb of additional armor, self-sealing fuel tanks. Armament increased to 1x 37 mm cannon (30 rounds), 2x .50 cal (200 rounds/gun) and 4x .30 cal (1,000 rounds/gun) machine guns. Provisions for a single 250-lb, 325-lb, or 500-lb bomb under the fuselage.
P-39Q-30 U.S.S.R. Version:
wing-mounted 0.30 cal machineguns replaced with a single 0.50 cal with 300 rounds of ammunition in a pod under each wing. These wing guns were often removed on Soviet aircraft. P-39Q-21 had a four-bladed Aeroproducts propeller. The P-39Q-30 reverted to a three-bladed propeller because the four-bladed unit worsened directional stability.
PS: P-39D should be classified as a US Army Aircraft, P-39Q-30 should be classified as Soviet VVS aircraft
